It’s pretty easy to project photos onto a wall—all you need is a decent projector.
If you’re a film junkie or a creative person who wants the fine details to be captured, a projector is proper.
Well, projectors are excellent — they are great, so you don’t have to worry if you can’t lay your hands on them.
The truth is, it is possible to project a picture on a wall without a projector.
You can project a picture on a flashlight or smartphone wall.
Here’s How to Project Laptop Screen to Wall Without Projector?.
Projecting An Image With A Flashlight
Point your flashlight at the wall and put the Fresnel lens (or loupe) before the lamp.
Turn on the light and let the lens shine. It will project the picture on the wall in this way.
Finally, the location of the lens has to be adjusted to focus on the image. Continue to change until the picture size and quality you like.
Projecting An Image On A Wall With Your Smartphone
If you are like most people, you probably believe that cell phones are used for routine calls and internet access.
Well, partially, that’s true.
The world has changed, and you can do a lot with your smartphone. Projecting a picture is one thing that you can do with your smartphone.
Let’s get it straight: no mobile telephone has an integrated projector setup. But you can use your smartphone to create an inexpensive Do-It-Yourself (DIY) projector by making specific changes.
Here’s how to do it.
First off, you’ll need the supplies.
- Knife or scissors precision
- Mirror
- Magnifying glass
- Ruler, pencil
- A shoebox or something like that
- Tape, brush, and glue with two sides
- Matte black colour or thick black paper.
#1. Use The Right Box And Mirror
You have to put a lens and a mirror in the package. This arrangement helps to construct a giant projected image with the light ray from your phone.
To get a brighter final picture, a lighter glass has to be reached.
You may also need a long box so that the distance between your phone and the projector lens can be adjusted. You will need a box that matches your phone screen as a general rule.
The mirror should be straightforward, rectangular, and equal to your phone.
#2. Blackout The Interior For Better Image Quality
Cut one narrow side of the outer box with scissors or a precision knife and keep it secure. Cut the box’s cover, too.
The reflection of light from the box walls contributes to the noise of the picture.
You have to cover the interior of your projector with black matt paper to avoid such a condition. It can be done only by glueing the black matte paper onto the inside walls of the projector.
It’s pretty quick to spread the glue over the black matte paper. You can do it with a brush.
You can choose to paint the box if you don’t have black matte paper. It would help if you let the paint dry after painting.
#3. Installing Your Lens Into The DIY Mobile Projector
Enter the length handle & trace its contour on the middle of the narrow side which has been cut.
Cut out the outline with your precision knife so that the lens fits into the hole.
#4. Design of your Phone Projector Manual Adjustable Focus
An adjustable focus means that a lens can be shifted to the phone.
You have to create a second box that fits into the outer box to increase the focus.
When the second box is made, create four black folds sheets of paper and place them on the box’s edge.
Caution: use an accurate measuring ruler.
Make some shallow cuts and fold the flaps at one end. Place the adjacent sides of the flaps with the glue. This arrangement makes the structure more robust and stiffer.
Next, glue the lens on the internal box flaps.
#5. Install the mirror in the Phone Projector Cardboard
You have a configuration that projects a picture left to the left & turns upside down.
Fixing the latter is simple — you have to disable the auto-rotating feature of your handset. After the function has been disabled, you can put your phone upside down.
A mirror may be used to correct the positioning of the left to the right image. You do this by putting the mirror on edge opposite the lens at a 45-degree angle.
#6. Create A Window For The Phone
Using your phone screen measurement, draw a rectangle above the mirror on the lid of your projector. With a precision knife, remove the rectangle.
Finally, in step 3, fit the lens into the hole. You’ve made your phone projection with this.
By decorating your phone projection with paint or some shiny material, you can become artistic.
Conclusion
In most large companies, workplaces, and public spaces, a projector is a required method. But if you want a fun, imaginative way to project a picture on a wall without a projector, you can only do so with a flashlight or your smartphone.
Building a personal spotlight is a fun way to engage your mind creatively. And you can do the job alone or invite a group of friends to help you achieve the position.
Yes, a DIY projector is not perfect and can’t make an ideal image. However, you can use it to project a picture on a wall during birthday parties and Halloween.
